Motorcycle

Abstract

A motorcycle has a head pipe, a pair of laterally spaced main frames extending rearwardly from the head pipe, and a receptacle supported on the main frames. In order to effectively utilize a space between the main frames, the receptacle has a bottom wall positioned between the main frames, the bottom wall having at least a portion positioned below a plane including an upper surface of the main frames.

We claim:

A motorcycle comprising: a head pipe;   a pair of laterally spaced main frames extending rearwardly from said head pipe;   a receptacle supported on said main frames;   said receptacle having a bottom wall positioned between said main frames, said bottom wall having at least a portion positioned below a plane including an upper surface of said main frames; and   said receptacle being shaped for storing a crash helmet therein.   
     
     
       2. A motorcycle according to claim 1, wherein said bottom wall is substantially flat and has a front portion positioned below said plane. 
     
     
       3. A motorcycle according to claim 2, wherein said front portion of the bottom wall is positioned near said plane. 
     
     
       4. A motorcycle according to claim 2, wherein said bottom wall has a rear portion which is wider than said front portion. 
     
     
       5. A motorcycle according to claim 1, wherein said receptacle is shaped for storing a crash helmet with a front face thereof directed forwardly. 
     
     
       6. A motorcycle according to claim 1, wherein said receptacle has a lid defining an upper wall thereof for opening and closing the receptacle, said lid being angularly movable about an axis extending transversely of the motorcycle. 
     
     
       7. A motorcycle comprising: a head pipe;   a pair of laterally spaced main frames extending rearwardly from said head pipe;   a receptacle supported on said main frames;   said receptacle having a bottom wall positioned between said main frames, said bottom wall having at least a portion positioned below a plane including an upper surface of said main frames;   said receptacle having a lid defining an upper wall thereof for opening and closing the receptacle, said lid being angularly movable about an axis extending transversely of the motorcycle; and   said lid having a smaller receptacle on its reverse side, said smaller receptacle being positionable in an opening of a crash helmet when said crash helmet is stored in said receptacle with the opening of the crash helmet being directed upwardly and said lid being closed.   
     
     
       8. A motorcycle comprising: a head pipe;   a pair of laterally spaced main frames extending rearwardly from said head pipe;   a receptacle supported on said main frames;   said receptacle having a bottom wall positioned between said main frames, said bottom wall having at least a portion positioned below a plane including an upper surface of said main frames; and   said receptacle having a lid defining an upper wall thereof for opening and closing the receptacle, said lid being angularly movable about an axis extending transversely of the motorcycle; and   an air cleaner case disposed behind and adjacent to said receptacle, and a cover having a substantially single outer configuration and covering said receptacle and said air cleaner case, said lid being a portion of said cover.   
     
     
       9. A motorcycle according to claim 8, further comprising a fuel tank disposed behind and adjacent to said air cleaner case, said fuel tank having a portion positioned inside of said cover. 
     
     
       10. A motorcycle comprising: a head pipe;   a pair of laterally spaced main frames extending rearwardly from said head pipe;   a receptacle supported on said main frames;   said receptacle having a bottom wall positioned between said main frames, said bottom wall having at least a portion positioned below a plane including an upper surface of said main frames;   said receptacle having a lid defining an upper wall thereof for opening and closing the receptacle, said lid being angularly movable about an axis extending transversely of the motorcycle; and   a rider's seat disposed behind and adjacent to said receptacle, said rider's seat having a front portion disposed in overlapping relation to a rear portion of said receptacle, said lid having a pivotally supported front end and a rear end positionable below said front portion of said rider's seat.   
     
     
       11. A motorcycle according to claim 10, wherein said rider's seat is pivotally supported on a frame of the motorcycle for angular movement about an axis extending longitudinally of the motorcycle. 
     
     
       12. A motorcycle according to claim 10, further comprising a smaller receptacle and an air cleaner case which are vertically arranged in front of and adjacent to said receptacle. 
     
     
       13. A motorcycle according to claim 12, wherein said smaller receptacle is detachably mounted on a frame of the motorcycle. 
     
     
       14. A motorcycle according to claim 1, wherein said upper surface of said main frames extends substantially parallel to a longitudinal axis of said main frames. 
     
     
       15. A motorcycle according to claim 1, wherein said storage receptacle is adapted to store a crash helmet with a lower opening of the helmet positioned substantially flush with said bottom wall of the storage receptacle. 
     
     
       16. A motorcycle according to claim 1, wherein said receptacle is shaped for storing a full face crash helmet with a front face thereof directed forwardly. 
     
     
       17. A motorcycle according to claim 1, further including: an engine; and   said bottom wall of said storage receptacle is positioned adjacent an upper end of said engine.   
     
     
       18. A motorcycle according to claim 1, wherein: said bottom wall of said storage receptacle is arcuately shaped complimentarily to an outer shape of a crash helmet to be stored in said storage receptacle.   
     
     
       19. A motorcycle according to claim 1, wherein said storage receptacle has cushioning means provided on an inner surface thereof for holding a crash helmet in a damped manner. 
     
     
       20. A motorcycle according to claim 1, wherein each of said pair of laterally spaced main frames has a substantially rectangular cross section with a width dimension thereof smaller than a height dimension thereof. 
     
     
       21. A motorcycle according to claim 1, wherein said receptacle includes means for preventing a crash helmet as stored therein from being moved about. 
     
     
       22. A motorcycle according to claim 21, wherein said receptacle includes a pair of laterally spaced sidewalls extending substantially vertically a width of the bottom wall of said receptacle being smaller than a distance between said vertically extending sidewalls at said portion of the bottom wall below said plane; and said means for preventing helmet movements comprises said small width portion of said bottom wall.
